CULTIVATING-HARROW.

of Letters Patent.

Patented Feb. 28, 1909.

Application filed December 14, 1907. Serial No. 406,544.

To all whom it may concern:

Be it known that I, JAMEs BRADFORD, citizen of the United States,residing at Nebo,'in the parish of Oatahoula and State of Louisiana,have invented new and useful Improvements in Cultivating-Harrows, ofwhich the following is a specification.

This invention relates to cultivating harrows, and the object of theinvention is to provide a simple and effective construction of combinedharrow and cultivator embodying movable or adjustable sections wherebythe width of the implement may be varied to suit conditions and wherebyalso the general shape of the harrow frame and the disposition of theteeth and shovels thereof may be varied to adapt the implement for useas an ordinary harrow, cultivator or side harrow.

'With the above general object in view, the invention consists in theconstruction, combination and arrangement of parts hereinafter fullydescribed, illustrated and claimed.

In the accompanying drawings :Figure 1 is a perspective view of acombined harrow and cultivator embodying the present invention. Fig. 2is a plan view of the same, showing the manner of adjusting the parts ofthe harrow to decrease the width or sweep thereof. Fig. 3 is a plan viewof the harrow extended to its full width also indicating by dotted linesthe manner of adjusting the parts to adapt the implement for use as aside harrow.

The frame of the harrow contemplated in this invention comprisesessentially a center or draft bar 1 provided at its forward end with ahook or clevis 2 and also comprising at its rear end upper and lowerpivot lugs 3 to which are pivotally connected the inner ends ofoppositely extending cross bar sections 4 and 5. At their outer ends thecross bar sections 4 and 5 are provided with pivot lugs 6 to which arepivotally connected the rear extremities of adjustable side bars 7 and8, which at their forward ends are adapted to be connected to the centeror draft bar 1 at any one of several points as will hereinafter appear.For the purpose of so attaching the side bars 7 and 8 to the draft bar 1the latter is provided with a plurality of holes 9, 10 and 11 adapted toreceive a bolt or other suitable fastener 12 which also passes throughthe forward ends of the side bars 7 and 8 as shown in the drawings.Harrow teeth 13 in any suitable number are mounted on the cross barsections 4 and 5 and similar harrow teeth 14 are secured to the sidebars 7 and 8 as clearly shown.

The usual arrangement of the parts is illustrated in full lines in Figs.1 and 3 wherein the cross bar sections 4 and 5 are arranged in line witheach other and extend straight across the machine perpendicularly to thedraft bar 1, while the forward ends of the side bars are connected tothe draft bar 1 in line with each other by means of the bolt 12. If forany reason it is desired to make the implement narrower, the bolt 12 isremoved and the ends of the side bars are set back to another hole atwhich )oint they are secured by the bolt 12 thus malring the harrowframe assume the shape shown in Fig. 2.

To adapt the in'lplen'rent for use as a side harrow, one of the sidearms 8 is connected to the draft bar 1 at a point further forward asshown in Fig. 3, while the other side bar is connected to a pointfurther back as shown in the same figure. In this position of the parts,the cross bar sections 4 and 5 while being in a straight line with eachother are disposed at an angle to the center bar as shown by dottedlines in Fig. 3.

From the fore oing dcscri tion, it will be seen that the impdement is acapted for use as an ordinary harrow, cultivator or a side harrow andthat the width of the harrow may be increased or diminished'to suitconditions. A strong connection is formed between the cross bar sections4 and 5 and the rear end of the center bar 1 and a thoroughly strongconnection is also afforded between the said side bars and center bar atthe forward end of said side bars, thus making a strong and durableconstruction.

Having thus described the invention, what I claim as new, is

An all metal implement of the class described, comprising a centraldraft bar disposed edgewlse vertically and provided with holes extendinghorizontally therethrough, cross bar sections extending in oppositedirections from the draft bar and connected ivotally thereto andconsisting of flat metal bars set endwise vertically, side bars of likematerial and disposition pivotally connected I In testimony whereof Iailix my signature at their rear ends to the cross bar sections and inpresence of two Witnesses. havin an independent adjustable boltedconneztion at their forward ends with the JAMES BRADFORD draft bar,metal teeth holding clips fastened WVitnesses:

to said side and cross bars, and teeth held by S. B. HARRIs,

said clips, substantially as described. J. R. TYSON.
